Abstract

T cell receptor (TCR) stimulation of naive CD8+ T cells initiates reprogramming of cis-regulatory landscapes that specify effector and memory cytotoxic T lymphocyte (CTL) differentiation. We mapped regions of hyper-accessible chromatin in naive cells during TCR stimulation and discovered that the transcription factor (TF) Runx3 promoted accessibility to memory CTL-specific cis-regulatory regions before the first cell division and was essential for memory CTL differentiation. Runx3 was specifically required for accessibility to regions highly enriched with IRF, bZIP and Prdm1-like TF motifs, upregulation of TFs Irf4 and Blimp1, and activation of fundamental CTL attributes in early effector and memory precursor cells. Runx3 ensured that nascent CTLs differentiated into memory CTLs by preventing high expression of the TF T-bet, slowing effector cell proliferation, and repressing terminal CTL differentiation. Runx3 overexpression enhanced memory CTL differentiation during iterative infections. Thus, Runx3 governs chromatin accessibility during TCR stimulation and enforces the memory CTL developmental program.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • TRM cells can be identified by upregulation of specific transcription factors such as HOBIT, RUNX3, and BLIMP-1, which lead to transcriptional reprogramming to downregulate tissue egress genes and upregulate tissue retention markers.

    “Additionally, T RM cells can be identified by the upregulation of specific transcription factors such as HOBIT (homolog of Blimp-1 in T cells), RUNX3 (runt-related transcription factor 3), and BLIMP-1 (B lymphocyte-induced maturation protein-1), which lead to transcriptional reprogramming to downregulate tissue egress genes and upregulate tissue retention markers. 295-298”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [297]

    The Discussion reports that Runx3 helps establish memory cytotoxic T-cell programs and is needed for normal Blimp1 expression. The passages concern circulating memory CTLs, however, not tissue-resident memory (TRM) cells; they do not establish HOBIT upregulation or the claimed downregulation of tissue-egress genes and upregulation of tissue-retention markers.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
